If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air
goes
out of a tire, it’s much more likely to leak out slowly. But
if you should ever have a “blowout:’ here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip
the steering wheel firmly.
Steer to maintain lane position, then gently brake to a
stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a skid.
In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle
to go. It may be
very bumpy and noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.
If your tire goes flat; the next section shows how to use
your jacking equipment to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage ~y
driving slowly to a level place. Turn on your hazard
warning flashers.
A CAUTION:
Changing a tire can cause an injury. The vehicle can slip
off the jack and roll over you
or other people. You and they could be badly injured. Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in “P” (Park).
3. Turn off the engine.
CAUTION (Continued)

If You’re Stuck: In Sand, Mud, Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels. The method known as “rocking”
can help you get out when you’re stuck, but
you must use
caution.

If you let your tires spln at high spe& they

the vehicle can &wheat. That could muse an
engine compartment fire or other damage.
When you’re stuck, spin the wheels 88 lltek adc

(55 Wh) as shown on the speedometer.
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will
clear the area around your fiont wheels. Then
shift back
and forth between
“R” (Reverse) and a forward gear,
spinning the wheels as little as possible. Release the
accelerator
pedal while you shift, and press lightly on the
accelerator
pedal when the transaxle is in gear. If that
doesn’t get you out after a few tries, you may need to be
towed out.
If you do need to be towed out, see “Towing
Your Buick”
in the Index.
